Topology-Aware Peer-to-Peer On-demand Streaming

Abstract

Abstract. In this paper, we consider large-scale high-bandwidth on-demand media streaming in a dynamic and heterogeneous environment. We present MetaStream, a scalable and distributed content discovery protocol that enables clients across the Internet to self-organize into a topology-aware overlay network, in which they can "cache and relay" a stream among nearby peers. We present the design and implementation of MetaStream and show experimental results obtained in a large-scale emulated environment. Our evaluation shows that MetaStream distributes relaying load among the clients in a topology-aware manner, imposing low link cost to the underlying network and low streaming load on the media server. MetaStream is also highly resilient to node or network failures and is capable of quickly recovering the streaming quality at clients even at high failure rates.

Providing VoD Services Based on Unstructured Overlay

“…But most of them use a tree-based overlay network, such as P2Cast [12], oStream [11], P2VoD [10], DirectStream [13], MetaStream [6]. Compared with the traditional methods, such as proxy, patching, and CDN, the treebased overlay networks achieve better scalability.…”

Challenges towards a Distributed Persistence Layer for Next Generation CSCW Applications

“…Other overlay networks like Can [13], Chord [17], Pastry [15,19] and Viceroy [10] share one of the basic features with tapestry. They are all based on distributed hash tables that provide useful load balancing properties depending on the built topology.…”

P2PVR: A Networked VCR Service for Live Multimedia Streaming

“…However, it remains a big challenge to select peers due to the heterogeneous bandwidth capacity of clients. There are several academic researches [1][2][3][4][5][6][7][8][9][10][11][12] and industry products [18][19][20][21][22] which propose different overlay construction mechanisms for peer selection. Most of these systems focus on the issue of constructing a robust and efficient P2P multicast overlay for live streaming.…”
